In a recent Mathematica StackExchange question, someone asked how such graphs could be automatically produced in Mathematica and code was quickly whipped up by the community. Since then, various individuals and communities have developed code to do the same thing in a range of languages. Here’s the list of examples I’ve found so far

I am putting together some fun technical slides and I wanted to use the xkcd code that you highlighted in your “Walking Randomly” blog. I have used this code before under version 8 a few months ago and it ran great. Under version 9 I have noticed an 800% slow down!?

I used AbsoluteTiming[] to get that slow down value between version 9 and version 8.

Are you seeing this performance change too? I am also wondering if I am perhaps doing something incorrect???
